Intel® C++ Compiler 9.0 for Linux*
Installation Guide

Contents

Introduction

This document explains how to install and configure for use the Intel® C++ Compiler 9.0 for Linux* product. Installation is a multi-step process. Please read this document in its entirety before beginning and follow the steps in sequence. For information about the product contents, including new and changed features, please refer to the separate Release Notes.

If you have a previous (lower numbered) version of the Intel C++ Compiler for Linux installed, you do not need to uninstall it before installing this version. If you choose to uninstall the older version, you may do so before or after installing this version. If you have version 9.0 installed, you can choose to replace the existing install or install to an alternate location.

System Requirements

Processor Terminology

Intel compilers support three platforms: general combinations of processor and operating system type. This section explains the terms that Intel uses to describe the platforms in its documentation, installation procedures and support site.

IA-32
IA-32 (Intel Architecture, 32-bit) refers to systems based on 32-bit processors from the Intel Pentium® family, (for example, Pentium® 4, Pentium® D, Celeron® or Intel® Xeon®), or processors from other manufacturers supporting the same instruction set, running a 32-bit operating system ("Linux x86").
EM64T
Intel® EM64T (Intel® Extended Memory 64 Technology) refers to systems based on IA-32 processors which have 64-bit architectural extensions, running a 64-bit operating system ("Linux x86_64") . Systems based on the AMD* Athlon64* and Opteron* processors running a 64-bit operating system are also supported by Intel compilers for EM64T-based applications.
Itanium®
Refers to systems based on the Intel Itanium® 2 processor running a 64-bit operating system.

Native and Cross-Platform Development

The term "native" refers to building an application on a platform type the same as the one on which it will be run, for example, building on IA-32 to run on IA-32. The term "cross-platform" or "cross-compilation" refers to building an application on a platform type different from the one on which it will be run, for example, building on IA-32 to run on Intel Itanium®. Not all combinations of cross-platform development are supported and some combinations may require installation of optional tools and libraries.

The following list describes the supported combinations of compilation host (system on which you build the application) and application target (system on which the application runs).

IA-32 Host
Supported target: IA-32
Intel® EM64T-based Host
Supported targets: IA-32 and Intel® EM64T
Intel® Itanium®-based Host
Supported target: Intel® Itanium®

Note: Development for a target different from the host may require optional library components to be installed from your Linux Distribution.

Requirements to develop IA-32 applications

Requirements to Develop Applications for Systems with Intel EM64T or AMD Opteron Processors

Note: The requirement for the 32-bit (IA-32) libraries is due to the compiler and other tools being 32-bit applications that dynamically link to these libraries. If these libraries are not installed, the following error may be displayed when the compiler is invoked:

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

The error message is confusing as it does not indicate that the IA-32 version of libstdc++.so.5 is required. To avoid this problem, be sure that the 32-bit (IA-32) versions of these libraries are installed. Most, but not all, Linux distributions for Intel EM64T will install these by default. Consult the documentation that came with your Linux distribution for instructions on how to install the 32-bit libraries, typically in packages named libstdc++ and libc.  If you still have problems, please contact Intel® Premier Support for further assistance.

Requirements to Develop Itanium-based Applications

We recommend using binutils 2.14 or later, especially if using shared libraries as there are known issues with binutils 2.11.

Notes:

Obtaining the Compiler and Tools

Before installing the compiler and tools, you should check the File Downloads section of Intel® Premier Support to see if a newer version or update is available. The version on CD or as listed in your electronic download license letter may not be the most current. In order to download and install a compiler from Intel® Premier Support, you will first have to register for support as described below in the topic Obtaining Technical Support.

Installing the Compiler and Tools

If you encounter difficulty with the initial installation or registration process, please visit https://registrationcenter.intel.com/support to request help from Intel.

Perform the following steps to install the compiler.

  1. Unpack the compiler package in a directory to which you have write access.
    > tar -xvf l_cc_c_9.0.xxx.tar
    or
    > tar -zxvf l_cc_c_9.0.xxx.tar.gz
  2. Run the installation script
    Execute the install script in the directory where the tar file was extracted.
    > cd l_cc_c_9.0.xxx
    > ./install.sh
  3. If you are not logged in as root, you will be asked if you want to install as root, install as root using sudo, or to install without root privileges. Installing as root (using sudo if you have that privilege) is recommended, as that will update the system RPM database. Select root, sudo or ignore - the last says to install as not root. Use the not-root install if you want to install to a private area.
  4. The install script will display a series of options. Numbered options (e.g. 1, 2, 3) are used to install specific components or tools. There may be some suboptions (e.g. 1a, 1b, etc.) which can be used to obtain additional information before installing. Type 1 and press enter to begin the compiler installation.
  5. You will then be prompted to enter your Intel C++ Compiler for Linux serial number. The serial number was provided to you when you purchased the product, either in an e-mail from the reseller or on a sticker attached to the CD-ROM package. You may also choose to enter a path to an existing license file. Make your selection and then follow the prompts.
  6. The install script then does some prerequisite checking and displays which Intel software development tools are installed, if any, and then offers a choice of a Typical Install or a Custom Install. Selection of a Typical Install is recommended - type 1 and press enter.
  7. Press enter again to display the license agreement. After the license agreement is displayed, you are prompted to accept or reject the license. If you accept the license, type accept and press enter. If you reject the license, type reject and press enter to end the install.
  8. The install will then continue - you may be prompted to accept further license agreements, specify install paths or to press enter to proceed through install steps.
  9. At the end of the installation, you will be prompted to register for Intel® Premier Support. Registration gives you full access to Intel® Premier Support for the length of your support term (typically one year for licenses purchased with support), including all updates and new versions. Without registering, you will be unable to install or use product updates. Enter your e-mail address, when prompted, to register. (If you already have an Intel® Premier Support account, enter its registered e-mail address.) You will then receive an e-mail with registration information including an initial password. If you do not wish to register, or if you have already registered, press x and press enter to exit.
  10. After registration, the install script exits.

Installation Warning for RPM 4.0.2 and RPM 4.1

RPM 4.0.2 cannot install to a non-default directory. This has been resolved in RPM 4.0.3. RPM 4.1 cannot install to a non-default directory. This has been resolved in RPM 4.11 to 4.2.

Eclipse* Installation Notes

Version 9.0 of the Intel C++ Compiler for IA-32 optionally installs the Eclipse* Integrated Development Environment (IDE) version 3.0.1 with C/C++ Development Tools (CDT) version 2.1.1, a Java* Runtime Environment (JRE) and the Intel C++ 9.0 compiler integration, which is required to use the Intel C++ Compiler within Eclipse. If you wish to use the Intel C++ compiler integration with your own instance of Eclipse, CDT and/or a JRE, you can. However, note that it is your responsibility to ensure that you are using the supported versions of Eclipse and CDT as well as a compatible JRE.

To use your own version of the JRE (rather than the JRE supplied in the 9.0 Intel C++ compiler kit) with the other Eclipse components supplied in the kit, do the following:

To determine if a JRE is compatible with a particular version of Eclipse, refer to the website www.eclipse.org . There you will find references to JRE kits that are supported with a particular version of Eclipse, as well as links to websites where JRE kits can be downloaded. Note that Intel has only tested the JRE supplied in the Intel C++ compiler kit.

Note: The Sun* JRE does not work with Eclipse and the Intel Eclipse integration on Itanium-based systems. JREs from JRockit* and IBM* are suggested alternatives.

To use your own instances of Eclipse, CDT and a JRE, you will need to create appropriate files and folders so that the Intel C++ compiler integration gets plugged into your pre-installed Eclipse environment. If you want to use the <install-dir>/bin/iccec file ( <install-dir> is the location where the Intel C++ Compiler is installed), you will need to make the following changes in the iccec file:

You can then execute the iccec script and your chosen versions of Eclipse, CDT and a JRE will be used. If you get an error regarding the loading of libraries, make sure that you have set LD_LIBRARY_PATH to include the appropriate folder in which Eclipse is installed

Installing the Intel License Server

If you have a floating, counted or node-locked license, the license must be installed in conjunction with the FLEXlm* license server for Intel software (Intel License Server), which is available for many popular platforms. The server may be installed on any supported platform accessible on your local network. The compiler CD contains license servers for several Linux distributions. If you do not have the CD, or need a license server for an additional platform, you can find all available license servers in the File Downloads section of your Intel® Premier Support account - select product Intel SW Dev Tools License Servers to find the server for your platform.

Installing the Intel License Server on SGI* Altix* Systems Running SGI ProPack* 3

If you will be installing the Intel License Server on an SGI* Altix* system running SGI ProPack* 3, please follow these alternate instructions to ensure correct operation in the partitioned cluster environment:

Setting Up the Compiler Environment

The programs in the Intel C++ Compiler 9.0 for Linux product rely on the environment variables PATH and LD_LIBRARY_PATH. The installation script (install.sh) creates compiler environment script files (iccvars.sh/idbvars.sh) that set these variables. It is strongly recommended that you add those script files into your login script (.login file). Once the variables are set in the ".login" file there is no need to run the script files for each session.

source the script to setup the compiler environment:

The installation program also creates compiler configuration files named <install-dir>/bin/icc.cfg that contain common settings for all compilations. You can edit these files to add additional default options. Note, if you install a compiler update package, you need to save the configuration file, if you have modified it, to another filename so that the installation doesn't overwrite your modified file.

If you have not already done so, please register for support after you install this product. See the topic Obtaining Technical Support below for registration instructions.

Uninstalling the Compiler and Tools

Please follow the steps below to uninstall the Intel Compiler and Debugger.

  1. If you installed as root, you will need to log in as root
  2. To uninstall the compiler:
    <compiler-install-dir>/bin/uninstall.sh
    or if you've installed the compiler to the default directory, use
    /opt/intel/cc/9.0/bin/uninstall.sh or
    /opt/intel/cce/9.0/bin/uninstall.sh on Intel EM64T-based systems
  3. To uninstall the debugger:
    <debugger-install-dir>/bin/uninstall.sh
    or if you've installed the debugger to the default directory, use
    /opt/intel/idb/9.0/bin/uninstall.sh or
    /opt/intel/idbe/9.0/bin/uninstall.sh on Intel EM64T-based systems
